ログインまたは登録しようとすると、Railsアプリケーションで以下のエラーが発生します（ログインにDevise GEMを使用しています）。

Routing Error
No route matches {:controller=>"devise/products"}

アプリケーションのすべてのソースコードはここにあります：https ：//github.com/rossmc/topsnowboards

application.html.erbとproduct/index.html.erbを次の場所から変更してみましたlink_to。

<%= link_to 'sign in', new_user_session_path  %>

に：

<%= link_to 'sign in', :controller => "/products", new_user_session_path %>.

しかし、これはさらに多くのエラーをスローします。

興味深いことに、前回のコミットでapplication.html.erbに配置したショッピングカートの部分を追加する前は、ログイン機能とルートは正常に機能していました。この部分を削除すると、ルーティングエラーは消えますが、部分的なviews / cart/_cart.html.erbが失われます。

以下は、ログインしてrakeroutesコマンドを実行しようとしたときのコンソールダンプです。これをご覧いただきありがとうございます。

それを見つけた？ログには、。までのパーシャルの束がレンダリングされたことが示されていますcart/_cart.html.erb。49行目でエラーが発生したこともわかります。49行目はどうなっていますか？これ：

<%= link_to 'Keep Shopping', :controller => :products %>
<%= link_to 'Empty Cart', :controller => "cart", :action => "clearCart" %>
<%= link_to 'Proceed to Check Out', :controller => "cart", :action => "createOrder" %>

Ryanが次のコメントで正しく指摘しているように、RailsはDevise、レンダリングしているものであるため、部分的にスコープが設定されているものを探しています。

もっと簡単に言えば、ヘルパーがURLを形成するためにrake routes追加するルート名（にあるルート名）をフィードするだけです。のURL文字列になります。_pathproducts_pathproducts#index

あなたの場合はどちらが

<%= link_to 'Keep Shopping', products_path %>
<%= link_to 'Empty Cart', clearCart_path %>
<%= link_to 'Proceed to Check Out', checkout_path %>

あなたのスタックトレースを聞いてください、彼らはあなたと話しているのです！

パーティーにかなり遅れましたが、これが私の解決策でした。コントローラの前に絶対プレフィックスとして「/」を付けるだけです。少し長くて醜いですが、コントローラー/アクションまたは渡されたルートのリンクを返します。SQLテーブルから駆動されるメニューを作成するために使用します。

  # dynamic link_to
  def menu_link(params, html_options=nil)
    if params[:controller].present?
      link_to params[:display], {controller: "/#{params[:controller]}", action: params[:resource]}, default_navigation_options(html_options)
    elsif params[:route].present?
      link_to params[:display], params[:route], default_navigation_options(html_options)
    end
  end
